The celebrity chef was kept out of schools as the district was uncomfortable with the reality TV concept; however, they invited him to help renovate menus, provided he leave cameras off campus. That left both sides at a stalemate.
"It's a big day, a really big day for a turnaround," said Oliver.
Deasy agreed to make a major change in the menu by banning chocolate and strawberry flavored milks currently sold at schools.
"One of the things that I've been very concerned about is flavored milk and additives into milk," said Deasy.
Oliver says the flavored milk has more sugar per ounce than a can of soda.
So Deasy is going to the Board of Education to recommend eliminating them from the cafeteria.
A plain 8-ounce carton of milk contains 14 grams of naturally occurring sugar known as lactose. It is also a good source of calcium, protein and vitamin D.
The chocolate milk has about a teaspoon and a half of sugar added, while the strawberry has about three added teaspoons.
LAUSD has been working with milk provider Driftwood Dairy to create a no sugar added flavored milk, utilizing chicory and a sweetener called Truvia. But it first must be tested by students.
Deasy and Oliver also plan to work together in other ways to help put the brakes on childhood obesity.
"He's the perfect man for the job. L.A. parents can be proud that the future looks bright," said Oliver.
